SPECIFICATION forming part of `Letters Patent No. 464,867, dated December 8, 1891.

Application filed July 20, 1891.

Serial No. 400,079. (No model.)

.To @ZZ whom t may concern.:

Be it known that I, CHRISTOPHER C. HAR- RIS, of Missoula, in the county ot Missoula and State of Montana, have invented a new and Improved Gage, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved gage, which is simple and durable in construction, being more especially designed for the use of carpenters and other mechanics to mark for hinges on doors and jambs to facilitate the hanging of doors. The invention consists of a bar provided witha fixed head and a movable head, an L- shaped guide-rod iitted to slide with one end on the fixed head, and a connecting-arm fitted to slide on the guide-rod and connected with the movable head.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of theimprovement. Fig. 2 is a front view of the same. Fig. 3 is a sectional side elevation of the same on the line a: a: of Fig. 2. Fig. l is a sectional plan view of the same on the line y y of Fig. 2, and Fig. 5 is a similar view of the same on the line .e .c of Fig. 2.

The improved gage is provided with a bar A, formed with a longitudinal slot A and with-a head B, having a transversely-extending tongue B', the said head being located near the Lipper end ofthe bar A. A movable head O is fitted to slide on the bar A, and is formed with a longitudinal tongue C', engaging the longitudinal slot A in the bar A. On

the movable head is also formed a transversely-extending tongue C2, arranged parallel to the tongue B of the lixed head B. An L-shaped guide-rod D is formed with the arms D and D2, of which the arm D extends transversely across the head B being provided with front face of the arm D to fasten the latter in position on the fixed head. In the other arm D2 of the guide-rod D is formed a longitudinally-extending dovetail groove D4, engaged by a tongue F, formed on one end of an arm F, extending transversely parallel to the arm D. In this arm F is arranged a transverse slot F2, engaged by the tongue O2 of the movable head C. A bolt G, similar in construction to the bolt E, passes through the slot A of the arm A, the head of the bolt resting against the back of the said bar. The bolt also passes through the movable head O and the slot F2, the wing-nut G of the said bolt abutting against the front face of the arm F to tasten the latter in position on the head C and the latter to the bar A. On the side of the bar A 4adjacent to the arm D2 of the guide-rod D is held a gage-plate Il for setting the gage according to the thickness of the hinge, to mark the proper place for the depth of the cut on the door or jamb. The gage-plate I-I is formed near its ends with parallel grooves H', engaged by screws I, screwing in the bar A and serving to hold the plate in the proper position, so that the distance between the front edge of the said plate and the rear side of the guide-rod D and arm F is equal to the thickness of the hinge for which the mark is to be made. On the same side of the bar A and near its ends are arranged points .l for securely holding the gage in place while marking the place for the hinge on the door or j amb.

The device is used as follows: In order to adjust the gage according to the width of the leaf of the hinge, the operator loosens both wing nuts E and G', and then slides the guide-arm D transversely until the distance between the inner edge of the arm D2 and the front edge of the gage -plate H corresponds with the width of the leal. The operator then screws up the wing-nut E to fasten the guide-rod D in place on the bar A. He then slides the head C and arm F toward or from the arm D until the distance between the arms D and F corresponds to the length of the leaf of the hinge. The wing-nut G is then screwed up to fasten the head C to the bar A and the arm F in position on the head The operator next loosens the screws I IOO and adjusts the gage-plate H, according to the thickness of theleaf of the hinge. The screws I are then screwed up to fasten the plate in .position on the side of the bar. The operator now places the gage on the door or jamb, with the pins J resting on the face of the door and Wit-h the guide-rod D placed against the edge of the door. The operator non?, with a pencilor other marking-instrument, follows the inner edges of the guide-rod D and the top of the arm F, then along the gage-plate H, thus laying off the thickness, width, and length of the leaf on the door or jamb.

It will be seen that when the gage is set for a certain kind of hinges no adj ustmentis necessary, and the operator can readily mark the doors and jambs at the propel-places for the accurate size of the leaves of the hinge. It will further be seen that no superfiuous pencil-marks are made on the door or jamb, as the operators tool for marking is conin ed Within the space of the gage, as above described, for marking the proper size. Hence the door or jamb are not unduly defaced.

The points J hold the gage in proper position While the operator marks the place for the hinge, as above described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A gage comprising a bar provided with a fixed head and a movable head, an L-shaped guide-rod held by one arm adjustably on the fixed head, and an arm for connecting the other arm of the guide-rod With the movable head, substantially as shown and described.

2. A gage comprising a bar provided with a fixed head and amovable head, an L-shaped guide-rod fitted to slide by one'arm on the said fixed head, a bolt for fastening the said arm of the guide-rod to the said fixed head, an arm fitted to slide longitudinally on the guide-rod and transversely on the said movable head, and abolt for fastening the said movable head and arnl to the bar, substantially as shown and described.

3. In a gage, the combination, with a bar formed with a longitudinal slot and a head having a transverse tongue, of a guide-rod formed with two arms extending at right angles to each other, the transverse arm being formed with a slot engaging the tongue on the said fixed head, a bolt for fastening the transverse arm of the guide-rod to the said fixed head, a movable head having a longitudinal tongue fitted to slide in the slot of the bar and also provided with a transverse tongue, an arm engaging the longitudinal arm of the said guide-rod and formed with a slot engag! in g'th e transverse ton gue'of themovable head,

and abolt for fastening the said movable head to the 'said bar and the arm to the said head, substantially as shown and described.

4. A gage comprising a bar, an L-shaped guide-rod held adjustably on the said bar, a connecting-arm for connecting the longitudi-v nal arm of the guide-rod with the said bar, and a gage-plate held adjustably on the said bar, substantially as shown and described.

5. A gage comprising a bar, an L-shaped guide-rod held adjustably on the saidbar, a connecting-arm for connecting the longitudinal arm of the guide-rodwith the said bar, a gage-plate held adj ustably on the said bar, and points held on the said bar on the same side as that on which the gageplate is held adjustable, substantially as shown and described.
